SUMMARY:Simplicial homology and wireless networks
DESCRIPTION:\n\n\n\nSimplicial complex representation gives a mathematical
 description ofthe topology of a wireless sensor network\, i.e.\, its
 connectivity andcoverage. In these networks\, sensors are randomly deployed
 in bulk inorder to ensure perfect connectivity and coverage. We propose
 analgorithm to discover which sensors are to be switched off\,
 withoutmodification of the topology\, in order to reduce energy
 consumption.Our reduction algorithm can be applied to any type of
 simplicialcomplex and reaches an optimal solution.In a second part\, we
 consider a damaged wireless network\, presentingcoverage holes or
 disconnected components\, wepropose a disaster recovery algorithm repairing
 the network. Itprovides the list of locations where to put new nodes
 topatch the coverage holes and mend the disconnected components. Inorder to
 do this we first consider the simplicial complexrepresentation of the
 network\, then the algorithm adds supplementarynodes in excessive number\,
 and afterwards runs the reduction algorithmin order to reach a unimprovable
 result. We use a determinantal pointprocess for the addition of nodes: the
 Ginibre point process which hasinherent repulsion between
 vertices.\n\n\n\n&nbsp\;
